1. Preheat the oven to 450 degrees F. Prepare a casserole dish (I used an 8x8" glass pyrex) with oil to cover the bottom. Set aside. Add 1 layer of potatoes to the bottom of the dish (I used 2 potatoes per layer, for 3 layers).
2. Add some sliced onions to the top of the potatoes, season with lots of salt and pepper, and add a few dollops of vegan butter on top of the layer.
3. Add the nutritional yeast to a bowl, and pour in enough milk or water (I used a mixture) to make a sauce (medium thinness). Season this with salt and pepper. Pour some of the sauce over the first layer, but remember you need enough for 3 layers.
4. Continue to layer the dish with potato, onion, salt, pepper, vegan butter, and cheezy sauce. You should have enough sauce to pour some on top. I recommend lots of onions on top because they brown so beautifully. Make sure you season with enough salt and pepper!
5. Pour some milk in the dish to about 1/2 up the dish. Bake for 45 minutes-1 hour (until the potatoes are very tender, and the sauce is bubbling).
Honestly, we could not tell any difference between this and the au gratin potatoes of our past.

SO HOW'D IT GO?

I made this for a potluck at school and everyone that I asked loved it, and would never have guessed that it was vegan! There is one downfall about the recipe, it's very, very salty. I never add any extra salt, so maybe it's the nutritional yeast? Who knows. It's still delicious though!

Okay, I am a cheesy potato snob, but since my daughter was diagnosed with a dairy allergy, I have been looking for good cheese and potato recipes. I just made this tonight and I must say that I was surprised at how good it was! I was worried when I smelled the nooch but it didn't taste like it smells at all. I used rice milk in my recipe as well. Next time I will add some fresh herbs to make it that much better. I think most non-vegan/vegetarians would have no idea that this is a vegan recipe. YUM!

Absolutely delicious! I forgot to add the vegan butter in between layers, remembering only when I put the last layer together. Despite this, it came out tasting super good! Will definitely make again and again!

I'm always nervous to try a new recipe because I want it to be as good as the reviews that I read. I tried this recipe today. I added smoked paprika and baked covered for 45 minutes and 15 minutes uncovered. They came out really good!

Okay, my sister and my hubby both loved this dish (both meat eaters, lol). :)>>> My sister said this was one of the best dishes she has ever eaten. I am the only vegan in the house so it is great to find dishes that both my family and I can eat, I usually end up cooking two different meals. I recommend everyone try this dish. I think next time I might add some spinach and facon ;) Thank you again for this wonderful recipe!
